Brake discs are the components of a motorcycle that are used for braking. They are located on the wheels of the motorcycle and consist of two planes on which the brake pads interact. When the motorcycle brakes, the brake pads stick to the brake discs, which generates heat and causes the motorcycle's speed to decrease.
Brake discs are made of different materials, such as steel, aluminum or titanium, and can be designed for different types of motorcycles. Brake discs should be checked regularly and replaced when worn or damaged to ensure effective and safe braking.
Signs of worn brake discs include:
If you notice any of these symptoms, it is important to have your brake discs checked by a mechanic, as worn discs can lead to reduced braking performance and can be dangerous. It is also important to check the wear of the brake pads, if the disc is worn and the pads are still thick, it is time to replace the disc.
It is not necessary to replace the brake discs every time the pads are replaced, as the discs can last much longer than the pads. However, it is good practice to check brake discs for wear or damage when replacing brake pads. It is common for brake pads to wear faster than brake discs, but in some cases discs may wear faster depending on driving conditions or the quality of the pads.
The service life of brake discs can vary depending on several factors, such as the type of motorcycle, quality and type of discs, riding style and road conditions. On average, brake discs should be replaced every 20,000 to 30,000 kilometers.
